It is 13%Cr martensitic stainless steel flux cored wire shield by CO2. It can use less of Cr and Ni to limit the harmful effect of the mechanical properties of ferrite. As there are Ni and Mo in deposited metal, it has higher strength and hardness. It can be used for joining more wear-resisting and corrosion resistanting materials for example: hydropower station, valves and other occasions which need wear resistance, and corrosion resistance such as ASTM CA6NM and the similar objects, small size of 410, 410S, 405, etc.
